Extremely lightweight 650B carbon wheelset!

The target of the development was nothing less than providing the best rim for fast and light-weight bikes. Nothing but the best!
For this purpose, Mcfk matched every parameter, every detail of the rim meticulously and did our utmost to develop the very finest for you.

Carbon for the rimIn contrast with aluminium, the advantage of carbon is that it stays in form. Thus, recentering, height and lateral runouts are things of the past. Once spoked properly, the wheel will not change shape or run.

Multiple layer designNo two types of carbon are alike. The layer design is the decisive aspect - the orientation of the fiber is the most important thing in any part made of carbon. For this reason, Mcfk use a complex mixture of fabric and unidirectional (UD) layers which are positioned exactly in the right direction to ensure that they get the best performance of the material and leave no potential unused.

Monocoque designAvoiding weak points was one of the central focal points in the development. Whereas Mcfk's competitors make the rim by bonding several parts together, their rim is laminated of a single piece and cured. This involves a higher input of time and effort and requires extensive know-how but adds stability, saves weight and produces a homogeneous rim.

35 mm outside widthThe wider the rim profile, the higher the lateral stiffness of the wheel.
The flexural rigidity increases disproportionately (to the third power) of the width of the profile. Mcfk's oversize rim profile on downhill rim level obtains stiffness never before attained with wheels of this weight class.

29 mm heightTo ensure high radial stiffness of the rim, a profile of sufficient height is needed to avoid radial load such as root carpets, bumps and bottoming from causing local bends and loss of tension of spokes.

3.5 mm asymmetryA very important aspect of the outstanding stability of our wheels is the distinct asymmetry of 3.5 mm. 3.5 mm asymmetry is the reason why the difference of the inevitably non-symmetrical position of the hub flanges to the hub center is reduced by 7 mm.
This ensures uniform spoke tension on both sides of the wheel.

24.5 mm inside widthWide tires require a wide rim. Both should make a good match otherwise the tire tends to cant and does not instill confidence while riding.

Rim flange with extra stabilityThe unique ratio of outside and inside widths also adds extra stability, width and solidity to the wheel flange. Bottoming - the enemy of any light-weight rim - need no longer be dreaded and so the life of Mcfk's carbon rims is extended.

Laminated spoke holesAnother very important advantage of their rims is the pre-compacted, laminated spoke holes, which are not drilled. This means no cutting of fibers, high spoke tension and therefore even more stability for the wheels.Besides, it gives the rim reliable protection from spoke tear-out in the case of a fall. You simply have to replace a couple of spokes but never the complete wheel.

Preformed ball head nipple tipTo ensure a perfect fit of the nipples in the rim, they need the right nipple seat. Because Mcfk do not drill the spike holes but compress and laminate them, they can shape a perfect ball head in the rim.

Tubeless-type rim wellThe days of "good-weather" hoses are numbered. With Mcfk's specially shaped rim well you can use any kind of tire. They most of all recommend the tubeless(-ready) models.

4 mm deep wellTo enable you to change tires without a tool as far as possible, they have made the deep well extra strong so you need less power and go easy on the material when mounting the tire.

Tune KingPS/Kong
The name of an Gorilla, weighing a ton, might sound a little martial for lightweight hubs. But it is strong as his namesake: No limit for biker weight.
Unique construction: due to adjustable play no bearing deadlock even at hardest lacing. Solid, uncomplicated, high-quality materials and precision bearings. Perfect manufacture - and absolute robust even under hardest conditions.

The new "King PS" for Predictive Steering forks is with not only light (152 grams), but with an oversize axle of 27.5 mm and special bearings also extremely stiff - what will be noticeable, especially with big 29 inch wheels.
Predictive Steering is a new hub standard, which was specially designed for the RockShox RS1 suspension fork, the hub spacing got increased by 10 mm (to 110 mm) and generally everything got sized bigger. The result is a more torsion-resistant hub-fork unit.

Tune uses special bearings which are like that not available on the market! The bearings identify themselves through a special grease and a higher filling degree. Besides o fit they are double abradant sealed and maintenance free.

The wheelset comes with mounts for 12 mm X-12 axle rear and 15x110 mm Predictive Steering front axle. Using optional Tune rear end caps can also be realized other standards.
